Abstract

Изобретение относится к устройствам, способам и системам, которые позволяют обнаружить и предотвратить образование трещин вследствие внутренних напряжений. Один из вариантов осуществления изобретения относится к устройству для обнаружения образования трещин в детали вследствие закалки при термической обработке детали, например, такой как индукционная закалка или газопламенная закалка детали, и/или вследствие правки детали, которое содержит акустический датчик, соединенный по корпусному шуму с деталью, при этом устройство выполнено для основанной на частоте и/или времени оценки акустических сигналов, зарегистрированных во время закалки или соответственно правки акустическим датчиком.The invention relates to devices, methods and systems that can detect and prevent the formation of cracks due to internal stresses. One embodiment of the invention relates to a device for detecting the formation of cracks in a part due to quenching during heat treatment of the part, for example, such as induction hardening or gas-flame quenching of the part, and / or due to dressing of the part, which contains an acoustic sensor connected by case noise to the part wherein the device is configured to evaluate, based on the frequency and / or time, the acoustic signals recorded during quenching or corrections, respectively, by the acoustic sensor.
